Life history responses of the small brown planthopper Laodelphax striatellus to temperature change
Journal of Thermal Biology, 2023Temperature is a key environmental factor in ectotherms and influences many life history traits. In the present study, the nymphal development time, sex ratio and wing dimorphism of the small brown planthopper Laodelphax striatellus were examined under the conditions of constant temperatures, naturally varying temperatures (or different generations ...

The small brown planthopper ( Laodelphax striatellus ) as a vector of the rice stripe virus
Archives of Insect Biochemistry and Physiology, 2022Abstract The small brown planthopper, Laodelphax striatellus , is a destructive pest insect found in rice fields. L. striatellus not only directly feeds on the phloem sap of rice but also transmits various viruses, such as rice stripe ...

The brown planthopper (BPH, Nilaparvata lugens), the small brown planthopper (SBPH, Laodelphax striatellus), and the white-backed planthopper (WBPH, Sogatella furcifera) are problematic insect pests and cause severe yield losses through phloem sap-sucking and virus transmission.

Roles of LsCYP4DE1 in wheat adaptation and ethiprole tolerance in Laodelphax striatellus
Insect Biochemistry and Molecular Biology, 2018The cytochrome P450 monooxygenase (P450) gene family has an important role in detoxifying host plant allelochemicals and pesticides. In this study, we screened differentially expressed genes of the small brown planthopper (Laodelphax striatellus, SBPHs) that were reared for more than ten generations on rice and wheat plants, and found that only a few ...

Mechanism of Fipronil Resistance in Laodelphax striatellus (Hemiptera: Delphacidae)
Journal of Entomological Science, 2014Abstract The WX-F strain of Laodelphax striatellus (Fallen) (Hemiptera: Delphacidae) was derived from a field-collected strain (WX strain) after 77 generations of continuous selection with fipronil. The selection resulted in 86.6-fold resistance to fipronil; WX-F showed no cross-resistance to dieldrin (1.8-fold) and low-level cross-resistance to ...

Musashi orchestrates melanism in Laodelphax striatellus
Insect ScienceAbstractIn insects, melanism, a fundamental pigmentation process, is of significant importance in evolutionary biology due to its complex genetic foundation. We investigated the role of the RNA‐binding gene Musashi (msi) in melanism in Laodelphax striatellus, a Hemiptera species. We identified a single L.

Male Killing Caused by a Spiroplasma Symbiont in the Small Brown Planthopper, Laodelphax striatellus
Journal of Heredity, 2013Spiroplasma-mediated late male killing was found in the small brown planthopper, Laodelphax striatellus. Female-biased colonies (maternal lines, N = 4) were established from planthoppers collected in Taiwan and Japan. This sex ratio distortion was maternally inherited (sex ratio of total number of progenies [female:male]: 488:0 in F1, 198:7 in F2, 407 ...

Wolbachia are the most common symbionts in arthropods; antibiotic treatment for eliminating the symbionts from their host is necessary to investigate the functions. Tetracycline antibiotics are widely used to remove endosymbiont Wolbachia from insect hosts.

Efficient detoxification is a key factor for the survival of pests exposed to insecticides. UDP-glycosyltransferase (UGT) is a superfamily of phase II detoxifying enzymes, which plays an important role in xenobiotics metabolism including insecticides.

Effect of temperature on the development of Laodelphax striatellus (Homoptera: Delphacidae).
Journal of economic entomology, 2013Temperature has a significant influence on the development of Laodelphax striatellus (Fallén), an important rice pest insect in east Asia. We set eight constant temperatures from 18 to 32 degrees C in 2 degrees C-increments to check the effect of temperature on the developmental rate of this insect species.
